(C# UWP/WinRT) SSL Client Certificate

Demonstrates how to connect to an SSL server using a client-side certificate, send a simple message, receive a simple response, and disconnect.

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

Chilkat.Socket socket = new Chilkat.Socket();

// Create an instance of a certificate store object, load a PFX file,
// locate the certificate we need, and use it for signing.
// (a PFX file may contain more than one certificate.)
Chilkat.CertStore certStore = new Chilkat.CertStore();
// The 1st argument is the filename, the 2nd arg is the 
// PFX file's password:
bool success = certStore.LoadPfxFile("chilkat_secret.pfx","secret");
if (success != true) {
    Debug.WriteLine(certStore.LastErrorText);
    return;
}

Chilkat.Cert cert = null;
cert = certStore.FindCertBySubjectCN("Chilkat Software, Inc.");
if (certStore.LastMethodSuccess == false) {
    Debug.WriteLine(certStore.LastErrorText);
    return;
}

success = socket.SetSslClientCert(cert);

bool ssl = true;
int maxWaitMillisec = 20000;

// The SSL server hostname may be an IP address, a domain name,
// or "localhost".  You'll need to change this:
string sslServerHost;
sslServerHost = "123.123.88.88";
int sslServerPort = 8123;

// Connect to the SSL server:
success = await socket.ConnectAsync(sslServerHost,sslServerPort,ssl,maxWaitMillisec);
if (success != true) {
    Debug.WriteLine(socket.LastErrorText);
    return;
}

// Set maximum timeouts for reading an writing (in millisec)
socket.MaxReadIdleMs = 20000;
socket.MaxSendIdleMs = 20000;

// Send a "Hello Server! -EOM-" message:
success = await socket.SendStringAsync("Hello Server! -EOM-");
if (success != true) {
    Debug.WriteLine(socket.LastErrorText);
    return;
}

// The server (in this example) is going to send a "Hello Client! -EOM-" 
// message.  Read it:
string receivedMsg = await socket.ReceiveUntilMatchAsync("-EOM-");
if (socket.LastMethodSuccess != true) {
    Debug.WriteLine(socket.LastErrorText);
    return;
}

// Close the connection with the server
// Wait a max of 20 seconds (20000 millsec)
success = await socket.CloseAsync(20000);

Debug.WriteLine(receivedMsg);
